[Russian, fist, kulak ("tightfisted landowner"), from Old Russian kulakŭ, fist, probably akin to dialectal Czech kulák, small stone (both Czech and Old Russian then being from Proto-Slavic *kulakŭ, fist, of unknown origin), or possibly of Turkic origin (akin to Turkish kol, arm, from Old Turkic kōl, upper arm).]
